To Kill the President: The most explosive thriller of the year. Sam Bourne

– that the woman had soon backed off. As for the rest, he reckoned they had simply not recognized him. He didn’t do the Sunday talkshows, he made few speeches. And that was just fine.

      Especially this morning. He would have struggled to pose for selfies, grinning broadly with the fanboys in their correctly coloured baseball caps. How they revered his boss. If only they knew what he knew, if only they had seen what he had seen just a few hours ago. (A grim thought surfaced: perhaps it would make no difference. Nothing seemed to shift their devotion to this man.)

      For the thousandth time he wondered if he had done the right thing. A backroom operative, he had never been a committed partisan. He had fallen in with this crowd simply because those were his friends and contacts. He had established a reputation as a man who could run things – big things – smoothly. After the army, everyone told him skills like his could make him a fortune. They were right. He went to New York, to one of the big financial houses, and was paid unimaginable sums. But he missed what he had loved most about the army: purpose. Politics seemed like a decent second-best.

      As for this job? He knew what prompted the offer: he would be presented as the responsible adult on the team, his calm, technocratic presence a token of reassurance to a nervous party establishment. It sounded old-fashioned but he felt it was his patriotic duty to say yes. If he hadn’t, one of the crazies surely would have. And, from the inside, he could perhaps act as a restraining influence, holding back a President who would otherwise be listening to the swivel-eyed extremists led by Crawford McNamara who clearly had the ear of the Commander in Chief.

      Now in the back of the car ferrying him to Manhattan, he closed his eyes, grateful to be cocooned, however briefly.

      Somehow, they had survived. The sun had come up, the sky had not fallen in. Civilization had not ended. For that he could not congratulate either himself or his closest ally, Jim Bruton. It wasn’t their intervention that had stopped the President giving the order.

      The truth was, he had been about to do it. The President had been put through to the colonel in the Pentagon War Room, who had, following procedure, issued the challenge code: Echo Bravo, or whatever it was. The President had responded, giving the codes that confirmed his identity: say, Delta Zulu. And then he had told the war room his decision, explaining that he had chosen from the menu of strike options and selected Option B.

      At that point – and kudos to him for the effort – the colonel had suggested that the President might want to consider going a la carte for this highly unusual situation. Highly unusual in that the United States was not under attack, the only scenario for which anybody had been trained or prepared. Nice try on the colonel’s part: ordering a special ‘dish’ would have taken hours or days. It would have bought Kassian and the others what they needed: time. But the President was adamant. Option B. Now.

      Apparently, there was a stillness in the room then. Even the President briefly stopped raging. The colonel turned to the team in the War Room and gave the signal. They set about formatting the ‘emergency action message’ that would unleash the forces reflecting the President’s choice – the bombs that would have destroyed the world. That task would have taken about a minute.

      But after about fifteen seconds, a young intelligence analyst told the colonel to wait. He had seen a report of a new statement from Pyongyang, apparently backing down on the earlier one that had so offended the President. It had just come in.

      The line connecting the Pentagon and the White House was still open and the colonel spoke. ‘Mr President, we have reason to believe the North Koreans have backed down.’

      ‘What’s that?’

      ‘Sir, they have fully capitulated. An abject apology.’

      ‘Are you sure?’

      ‘That is our information, sir, yes.’

      ‘OK.’

      There were twenty seconds left till the action message went live.

      ‘Does that mean you wish to abort the order, sir?’

      ‘What did the North Koreans say exactly?’

      ‘Sir, we have ten seconds to decide. Should I abort the order?’

      ‘Fuck them.’

      ‘Sir?’

      ‘All right, all right. Abort.’

      And that’s how they had averted Armageddon. One sharp-eyed desk officer may well have saved the world. Quick-witted and creative, more than sharp-eyed, as it turned out. Jim Bruton arrived at the Pentagon minutes afterwards, where the colonel on duty discreetly let him know him that the supposedly abject statement from North Korea, fortuitously released just seconds before the trigger was about to be squeezed, was more a work of wishful thinking than reality. The analyst had correctly read the situation, understanding that his immediate commanding officer and the Defense Secretary were desperately looking for an excuse to delay, and he had provided them with what they needed. In the process, he had left Bruton with a new headache – he now needed to generate a text that looked plausibly like a full apology from Pyongyang – but, given the stakes, that could be forgiven. Jim had immediately recommended the officer and the entire duty team in the War Room for a Defense Superior Service Medal.

      Kassian had now reached the Waldorf Astoria hotel. Without looking either left or right, he made straight for the elevators, letting his Secret Service agent clear a path, press the button and select the floor. Avoiding eye contact with hotel guests, he caught himself in the mirror. He retained a full head of hair, but it seemed to be greying by the day. Back in January, it was all dark. He was still tall, still lean. His wife insisted he remained handsome: ‘Real handsome, not Washington handsome,’ was how she put it. But what he saw in his eyes was something else: a look of alarm and worry that was becoming permanent. The face staring back at him seemed haunted.

      They stepped out on the fifth floor and went to the suite whose number he had been given. They were let in by a warm, rounded blonde woman in her mid-forties who introduced herself as the Swedish ambassador to the United Nations. She struck him as unexpectedly maternal.

      There was an awkward moment or two as Kassian’s agent checked for security, including – especially – for bugs. Then the agent was introduced to his counterpart, who did the same. Only when both were satisfied, and had nodded in the direction of the Swedish host, did she give the signal that, a second later, meant a door – presumably to one of the bedrooms – was opened. Through which stepped out a man Kassian recognized as the Ambassador to the United Nations of the People’s Republic of China.

      Kassian, still standing, offered his hand, which the Chinese diplomat took firmly. Kassian knew the man was just a year older than he was: fifty-one. He wore a plain blue suit, an off-white shirt and oversized, 1970s-style glasses. No retro chic was intended. They were just old.

      Their host gestured for them both to sit down in the living area – two couches, armchair, coffee table – at the centre of the suite. In an accent that suggested an expensive education in England, she spoke first.

      ‘Gentlemen, as you know, we were asked to make a space available for you to talk in a way that would remain completely unrecorded and confidential. It was Mr Kassian’s suggestion that you meet here, rather than in Washington, where he suspected discretion would be harder to achieve, especially perhaps for him.’ She smiled. ‘He was also aware, with all due respect to the Republic’s ambassador in Washington, that you, Mr Lei, are widely reputed to be even closer and, dare I say, more influential with your government in Beijing.’

      She paused and continued. ‘I should stress that Sweden has no selfish interest of our own in whatever issue has brought you both here. But you will both be aware of Sweden’s great and historic interest in advancing the cause of peace in the world. If there is anything that can be done to avoid war, then my country will give whatever we can.

      ‘I repeat that what is said in this room will remain confidential. No word of it shall be spoken by us. We will deny this meeting ever took place. No one knows any of us are here. This room is booked in the name of an anonymous Swedish businessman. As
